Construction using bundled tube and threaded stepped dowels

Abstract

A system and method for creating a column for construction using bundled tube are provided. The column having a bottom portion, a middle portion, and a top portion. Each portion consists of a bundle of individual pillars, comprising a center pillar, a plurality of corner pillars, and a plurality of middle pillars. From the bottom portion of the column, addition pillars can be affixed on top of the pillars of the bottom portion, thus forming the middle and the top portion of the column. Each pillar can be secured to another component using a thread stepped dowel comprising of a base section, at least one middle section, and a tip section, with each section being progressively smaller in circumference than the last. The at least one middle section of the threaded stepped dowel further comprises thread spiraling around the outer surface of the at least one middle section.
